System-Specific DDR5 Kit for Supermicro H14DSG-OD

This 384GB kit contains six 64GB DDR5 RDIMM modules built for the Supermicro H14DSG-OD motherboard. It targets administrators upgrading memory capacity in compatible servers. The registered ECC design meets enterprise reliability requirements for production workloads.

Registered ECC DDR5 6400 CL52 2Rx4 at 1.1V

The decisive specification is the 2Rx4 registered ECC configuration running at DDR5 6400 with CL52 latency and 1.1V. This exact rank, voltage and timing combination matches the memory controller expectations so the system recognises the full 384GB at rated speed.

Six 288-Pin RDIMMs Populate Compatible Slots

Six 288-pin RDIMMs fill the supported DIMM slots on the H14DSG-OD following the board's population rules. Registered buffering offloads the memory controller for stable fully-populated operation while ECC corrects single-bit errors. Verify the manual for approved population order before installation.

Questions about this item

What does the 6400 MT/s rating actually deliver when all six slots are populated?

The kit runs at DDR5-6400 with CL52 timings at 1.1 V across all six registered DIMMs, giving the full 384 GB capacity at rated speed.

How does the registered ECC design affect the memory controller on this motherboard?

Registered buffering reduces electrical load on the controller so every slot can run fully populated, while ECC corrects single-bit errors in real time.

Will these 288-pin RDIMMs physically seat in the Supermicro H14DSG-OD?

Yes, the 288-pin registered form factor matches the board's DDR5 RDIMM slots exactly.
